CHARGING MACHINE FOR BOTTLE MANUFACTURE Patented July 2, 19 35 UNITED STATES CHARGING MACHINE FOR BOTTLE MANUFACTURE Heinrich Severin, Sasbach, near Achern, Baden, Germany Application December 5, 1932, Serial No. 645,791 In Germany December 16,1931

10 Claims.

This invention relates to a charging machine which receives from the general transporting means the bottles accruing at a glass furnace and deposits them in an upright position entirely without shock in an annealing furnace in the usual manner.

The bottles may vary in diameter within wide limits, which are only dependent upon the construction of the machine and the breadth of the belt conveyors. It is also immaterial whether the bottles to be stacked are round or angular, and whether they are large or small. The machine may be built for an annealing furnace of any breadth and is adjustable within wide limits in this respect. The maximum output of the machine described in detail below amounts to thirty bottles per minute. If the requirements exceed this figure, which corresponds to an output of about forty-three thousand bottles per day, it is advisable to adopt a construction comprising three distributor arms or to provide each transport arm with two or more transport tracks which can be charged one after the other, and bringthe bottles into a common erecting device, tipping trough or the like.

One form of construction of the invention, comprising two distributor arms, with one transporting track on each distributor arm, is illustrated by way of example in the accompanying drawings, in which Figure l is a side View, 7

Figure 2 is a side section through the centre,

Figure 3 is a view from above, with half the cover plate of the machine base removed,

cover plate and the drive omitted, and

Figures 5, 6 and 7 show the erecting head serving for setting up the bottles with the displaceable tipping trough, Figure 5 being a side view with the tilting trough rocked up, Figure 6 a plan, and Figure 7 a section on the line 1-'I in Figure 5. For the sake of clearness, only those parts that are necessary for the comprehension of the method of working of the machine are hereinafter referred to by reference numerals, and specified in detail.

The machine illustrated in Figures 1 to 4 comprises two distributor arms 5 and 5a, which are substantially duplicates of one another; The various parts of the distributor arm 5a shown in Figure l, in the lower part of Figure Band the right hand half of Figure 4 are distinguished, by the addition of the letter a to the reference numeral, from the corresponding parts of the distributor arm 5, shown in Figure 2, in the upper Figure 4 is a View from the rear, with half th part of Figure 3 and the left-hand half of Figure 4.

The charging machine consists of a base I, running to the furnace on rails and accurately adjustable in height. The base carries in its upper cover plate two slide guides 2 and 2a, in which slides 3. and 3a respectively are guided.

At the end of the slides facing the furnace the two distributor arms 5 and 5a are so supported in frames 4 and 4a as to be horizontally rotatable about pivots i5 andfia.

At the lower end of the pivots 6 and 6a of these arms 5 and 5d are fixed levers I and la respectively,'which are guided with rollers 8 and 8a fitted to the other ends thereof in longitudinal guides 9 and ha in slide pieces In and ma respectively.

These slide pieces are guided upon pairs of slide rods 4 i and Ma fixed in the base, and have on theirunder side rollers l2 and I2a, which. are pushed to and fro by worms I 3 and l3a rotating to right or left according to the movement of the arms. i

The slides'3 and 3a carry belt conveyors I4 and Ma and the distributor arms 5 and 5a carry belt conveyors i5 and [5a serving for the rapid feeding of the bottles. I

At the ends of the distributor arms 5 and 5a projecting into the annealing furnace are suspended depositing or'erecting heads l6 and Mia respectively, asshown in Figures 5, 6 and '7;

The depositing head it consists of a tipping trough l1, displaceable forwards in a horizontal direction, a tipping frame 29, which is supported by pivots 2| in side plates I 9, and brackets 22 for the bottom plate 24 swinging about a pivot 23. The bottom plate isfixedly connected with an abutment lever 25. I I

The tipping frame 20 holds at both ends two slide rods upon which two slide shoes 27 connected by a plate 23 are slid to and fro. The slide shoes are guided by rollers It in slots in the side plates IQ of the depositing head.

This connecting plate 28 comprises guides 29, in which there slide four round rods 30, to the ends of which the tipping trough I? is secured by means of a holding plate 94. 7

Upon the tipping frame 20 is fitted a bracket 33. In this bracket 3i and the cover plate 32 of the tipping frame 29 are supported two pivot bolts 33, to which are secured on the onehand two wings 3 3, and on the other hand two small levers 35. These levers are guided by suitable pins 36 in slots 3'! in the connecting plate 28,

and when these are displaced the wings 34 open, and when they are slid back the Wings close.

To the connecting plate 28 is also fixedly connected the bearing for the pivot bolt 38, to which is attached a guiding link 39 pivoted to a connecting rod 40 by a bolt 4|.

The entire depositing head can be exchanged at any time in a few minutes after releasing the bolt 38 or the bolt 4| from the guiding link 39 at the conclusion of an operating period, simply by lifting off one head and hanging on another.

The depositing head l6a is identical with the depositing head It in construction and operation, its various parts being distinguished from those of the depositing head it by the addition of the letter a to the reference numerals.

Above the end of themachine base remote from the annealing furnace, is erected a feeding conveyor 52, which is directly connected with the general conveying means running from the glass furnace. At the discharge end of this feeding conveyor switch points 43 are provided, which are pivoted to a vertical shaft 44, and which distribute the bottles, acording to their position, to the belt conveyors i4 and I4a of the slides 3 and 3a through two chutes 45 and 45a.

Between these switching points 43 and the end of the feeding conveyor 42, an arm 41 provided with a catch 45 is so suspended as to be able to swing vertically. With the catch 46 there engages a horizontal arm 49, which is supported at 48, and which is provided with a pawl hook 51 carrying a roller of material which is a bad conductor of heat. To the arm 43 is secured at its pivotal point a mercury tilting contact 52. The arm 49 also has an abutment 53, against which the end of a thrust rod 54 is directed.

The drive for the whole of this apparatus is obtained from an electric motor 55, but may alternatively, where conditions permit, be obtained from the motor of the annealing furnace, in such a way that the forward displacement of the annealing furnace belt conveyor 56 is positively controlled by the charging machine. The shaft 51 of the motor drives through counter-shaft gearing 58 a main shaft 59, upon which are mounted fast all those eccentric sheaves and cam discs which influence the distribution of the bottles accruing to the distributor arms, the lateral advance of the arms, with the depositing head, and the depositing of the bottles.

Loosely grooved on to this driving shaft are two sleeves 6!] and 69a, which, by means of two eccentric" sheaves or cam discs 6! and 62 secured to the sleeve 6!] and two eccentric sheaves or cam discs Ma and 62a secured to the sleeve a, determine the forward and backward movement of the slides 3 and 3a, and thereforeof the distributor arms and of the depositing heads, as Well as the reversing points in the lateral displacement of the latter.

The coupling between the shaft 59 and the sleeves 6E! and Ella is effected in the following manner. Upon the shaft 59 are mounted two discs 63 and 53a. Each of these discs carries a number of driving pins, eight in the present instance, adapted to mesh with star wheels mounted fast upon shafts. The driving pins only occupy half the circumference of the disc in each instance, and are so arranged that while the pins 64 on the disc 63 are driving the star wheel 65 and its shaft 65, the pins 64a on the disc 6311 are out of engagement with the star wheel 65a, so that the shaft 66a remains stationary, and conversely. Hence the shafts 6B and 6611 are driven intermittently and alternately.

These shafts, through toothed wheels 6? and 61a mounted fast thereon and various transmissions 68 and 88a, actuate toothed wheels 69 and 69a mounted fast upon the sleeve,s0 that the eccentric sheaves and cam discs SI and fila, 62 and 62a, mounted fast upon the sleeve, also ad- Vance intermittently from time to time through a distance determined by the transmission ratio, and then come to a standstill again until a further impulse is imparted by the pin wheel gearing, this movement occurring at the right hand and left hand sides of the machine alternately. There are furthermore mounted upon each of the shafts 68 and 65a to which the star wheels 65 and 65a are secured, two toothed wheels if) and 10a, H and 1 la. These mesh, in one case directly and in the other case with reversal of the direction of rotation by the interposition of a pinion T2 or 12a, with the toothed wheels 74 and 14a, i5 and 15a, mounted loose upon the shafts l3 and 113a. Upon the shafts i3 and 73a there slide dog clutches l6 and 16a, which rotate the shaft either in a clockwise or in an anti-clockwise direction according to the position of the clutch. The shafts l3 and 13a, through the toothed wheels I! and Na mounted fast thereon and the various transmission devices 18 and 18a,

tion of movement, of the rollers 12 and lid guided in the worms i3 and 13a, and therefore of the levers 7 and la of the distributing arms and of the depositing heads I6 and IEa.

The motor shaft 5'! drives through bevel gearing a vertical shaft 81 and a bevel wheel 32, and through the latter a horizontal shaft 83, from which the driving of thefeeder 42 and the slide conveyors l4 and 14a is effected by chain transmission. The driving of the band conveyors i5 and lea of the distributor arms is effected through the medium of chains 34 and 84a, actuated by horizontal shafts 86 and 36a, splined in the hubs of bevel wheels 85 and 85a meshing with bevel wheels mounted fast on the transverse shaft 83.

Behind the bevel gear 80 there is fitted into the driving shaft 51, an electromagnetic clutch 5?, through which the motor shaft 5'! drives the countershaft gearing 58 0f the main driving shaft 59, the switching of this clutch is effected primarily by the mercury contact 52 and transiently by a short sliding contact 99, fitted to one of the eccentric sheaves.

This machine operates in the following manner: Of the bottles that pass out of the main transporting means onto the feeding conveyor 32 the first strikes against the pendulum 41, releases the catch 46, and slides through underneath the roll-er 50 of the pawl lever 49, is guided by the switching points 43 to the slide conveyor l4, and is fed by the latter to the belt conveyor l5 of the distributor arm 5, where it slips into the tipping trough H of the depositing head, which is then in the nearly horizontal position shown in Figures 1, 5, 6 and 7. As soon as the bottle has released the catch 45, and the pawl lever 49 has fallen down, the circuit is closed by the tilting of the mercury contact 52, and the electromagnetic clutch 8 1 has set the driving shaft 5% in rotation through the medium of the transmission gear 5. ljh s ar 64 of th -i-se :63 new en a s with he teet of the a whee nd rotates, w th th shaft th va ooth d wheels .61, 1,0 and H, the sleeve- .60, and tlileweccentric $1 mounted fast thereon, some distance forwards. This eccentric controls the advance and the retraction, which starts at the point of reversal, of

' the slide 3, the movementof rapid retraction beins f cted. und r he pull of a p wh l 'the forward movement is obtained from a lever .89 by means of .a connecting rod 88. According as the connecting rods 88 and 8.8:; are pivoted in one .or other of the holes provided at the upper ends of the Levers 89 and 89a the amplitude of the forward thrust varies so as to adapt the mov m nt t th avera d ame o he bo l to introduced.

Eurthermore, by the rotation of the star wheel shaft 66, the two toothed wheels 74 and I5 mounted loose upon the shaft l3 are rotated in opposite directions. According .as one or the other is connected by the dog clutch it with the shaft is and its counter-shafts T8, the worm is revolves a little further each time either in one direction or the .other.

The reversal of the direction, which is always effected when a row of bottles is completely deposited, is effected by displacing the dog clutch 75, this displacement being controlled by the eccentric sheave 62a li ewise mounted fast upon the sleeve 59a, by means of the lever mechanism a, the eccentric sheave on the right hand side of the machine in this 0.358 controlling the clutch on the left hand side, and conversely.

By suitably selecting the pitch of the dog clutch relation to the pitch of the star wheel 55, the result is obtained that .every time the dog clutch is reversed, a tooth on one side positively stands exactly opposite to a space .on the other side, It will be evident that the further the star wheel 35 is rotated upon its shaft 56 the greater will b the fo w rd fe d of he ormi eeh rs n ma ine of t e c nst u t on fi strated the eight driving pins of one half of the discs 53 and (63a, with ,a transmission ratio .of 1:2, rotate the star wheels 55 and through one complete revolution, which correspondfi to a lat ral m vem n o t di tri u d positing head amo nting to 80 millimetres; ,or in other words the machine isbuilt, in its present construction, for the depositingof bottles having a maximum average diameter of .80 millimetres, If the diameter is greater than .80 millimetres, which would only occur quiteexceptional cases, the transmission ratio .of the pin gearing would have to be taken correspondingly higher, which can be effected without difficulty by changing the two .discs and wheels.

In general, however, it will be suff cient to pro.- vide for a maximum average diameter .of the bottles accruing from the furnace of 80 millimetres, and most cases it will be less than 8.9 millir metres, Just, as, in such cases, the forward feed= ing of the slide is regulated by suitably diminish? 133% the effective length of the arm of the lever .39, the smaller bottle diameters, which involve a smaller lateral advance of the depositing head, can be allowed for by providing a smaller number of drivi g pins than the existing eight on the discs 6.3 and -53a. It will be immediately obvious that if eight driving pins .eifect one complete revolution of the star wheel .65 or Ma, and. therefore a lateral advance of the depositing head amountns .0 mil etres, seven driving time will only diameter of the bottles to be deposited, therefore, only the number .of driving pins necessary for this average diameter need be provided in the discs 63 and $311, each driving pin corresponding to an advance of .1 centimetre.

If smaller differences are desired, these are easily obtainable at any time by making the pitch of the pin gearing finer,

The speed of revolution of the shaft 5.9 is so related to the speed of travel of the belt conveyors id, Ida and I5, I So that a bottletravels from the pendulum lever 41 to the tipping trough ll of the depositing device while the shaft .59 is executing nearly half a revolution. By the time this half revolution is terminated, an eccentric 9i mounted fast thereon, by means of a connecting rod Ed, has returned the pawl lever 43.9 into its original position in the catch 46 again. The mercury contact 52 is thereby returned to a horizontal position and interrupted. The electromagnetic clutch $7 is disengaged, and, while the motor of the band conveyors 112, I4, 14a, .45 and lid continues .to run, the driving shaft .59 is stationary until a second bottle releases the catch 4 .6 and repeats the series of operations previously described on the other side of the machine. While now this second bottle, with steady advance of its distributor arm 5a is fed forwards and sideways to its tipping trough Ila, the first distributor arm 5 is stationary, and the bottle is deposited in an upright position upon the place allotted to it. For this purpose the connecting rod dd under spring pressure is slid forward. By the guiding link 39 the tipping frame 259 is tilted and takes up a horizontal position, as shown in Figure 2, the rollers 18 .of the slide shoes 2111.011- m upward along the segmental dots in the side plates is. Now upon furtheradvance the slide sho es,with the .connecting plate 28,.are pushed forward upon their slide rods .25, as .a result of which the two levers .35, and therefore the wings 34 are openedas shown in the case of the wings 54a in the lower half of Figure An abutment .92 on the connectin plate 28, in which the four front guides for the four carrying rods .29 of the tipping trou h l! are located, i pushe o t t r a side of the trough and be ins to slide the bottle forwards gently and without shock, While at the same time the'bottom plate 2:}, the lever 25 of which has been set free from the stop 53 on the conne tin p a 2.8 d r n th fort-y rd s d volving round the shaft 3, rests upon the annealing furnace belt conveyor 56, so that the bottle is prevented from overturning. The pushing forward of the bottle is vcfiected i nder spring pressure and is adjustable. When the bottle is standing in its place, the connecting rod to is quickly drawn back. The tipping trough I? at fir t m es back upr ht o a horizontal tion, until its carrying plate 9.4 strikes against the co e pl e s of h t pping frame 0. Th du i g f rt er retra ion of t e sl de Shoes the little pins 38 slide inwards in the recesses ,3? in the connecting plate 28 and close the wings 54. The r l ers it h arrived at h end of h h rizontal rectilinear uide, and .upon further ret ti n o the nn c ing d 413 the tippin frame 28 tilts about its pivots 2} back into its original receiving position.

Meanwhile the second bottle has arrived in its tipping trough Fla, and the mercury contact 52 has been returned into a horizontal position and disengaged.

Now it is by no means contemplated, however, to interrupt the running of the machine and bring it to a standstill every time a bottle is deposited, thereby necessitating a fresh start every time. Instead of this the speed of revolution of the continuous current motor 55 is so regulated that the machine works a little more slowly than corresponds to theaverage interval between two arriving bottles. Furthermore there is provided on one of the eccentric sheaves mounted on and revolving with the shaft 59, on the sheave Si for example, a short auxiliary contact 99, not shown, which still delivers current to the motor 55, after the pushing up and switching oil of the mercury contact 52, until the half revolution of the shaft 59 is fully completed. If

7 therefore in the time between the pushing up of the mercury contact 52 and the running oiT of the half revolution of the shaft 553 a bottle rrives upon the feeding conveyor 52 and releases the catch 45, the charging machine continues to run without interruption.

There is however no objection to a small supply of about two or three bottles accumulating upon the feeding conveyor 42, since the waiting time only amounts to a few seconds. In this case a bottle is always ready, after being freed by the pawl lever 49, 5!, to release the catch 48 at the right time, so that a stoppage of the machine only occurs when the operating of the glass furnace is interrupted. It is advisable in this case, in order to render any supervision unnecessary, to provide above the resting position of about the third of he bottles accumulate-d upon the feeding conveyor 42, a thermo-couple H19, or any other contact actuated by the recumbent bottle, in the neighbourhood of the bottle body, as a result of which, through the medium of a relay for instance, more current is immediately supplied to the motor 55, and its speed of revolution thereby increased, so that the number of bottles accumulated. upon the feeding conveyor 42 is quickly reduced to two again.

A special advantage of the machine is its rapid adjustability to different sorts of bottles and its adaptability to annealing furnaces of different breadths. To adjust the aggregate angle of oscillation of the distributor arms to the width of a particular annealing leer the moment of retraction and reversal of swing must be altered. .Retraction obviously takes place twice for every revolution of the cam disc 6| or Sid; and reversal takes place at the same moment owing to the shifting of the dog clutch 16 or 15a by the cam disc 62a or 52; the cam discs 6! and 52 being mounted fast upon the sleeve 60, and the cam discs Btu. and 62a. upon the sleeve 65a. It is therefore necessary to alter the transmission ratio between the shaft 59 and the sleeves 5D and 69a.

In order to enable this transmission ratio to be easily altered, the two wheels a and I) pertaining to the transmission gear 68, 6811 are made readily accessible and exchangeable on the outside of the machine frame I.

As soon as this charging machine has been definitely adopted in practice, the forward feeding of the annealing furnace belt conveyor 56 will doubtless be made controllable by the charging machine, since only by this means is an absolutely complete utilization of the space available for annealing ensured.
